AWS Lambda vs OpenFaaS: What are the differences?
Key Differences between AWS Lambda and OpenFaaS
AWS Lambda and OpenFaaS are both serverless computing platforms, but they have some key differences that set them apart.
-
Deployment and Hosting: AWS Lambda is a fully managed service provided by Amazon Web Services, which means that AWS takes care of the underlying infrastructure and hosting. On the other hand, OpenFaaS is an open-source framework that allows you to deploy and host functions on your own infrastructure or on third-party cloud providers.
-
Programming Languages and Runtimes: AWS Lambda supports a wide range of programming languages, including Node.js, Java, Python, and more. It also allows you to use custom runtimes to run functions in any language. OpenFaaS also supports multiple languages, but it relies on Docker containers, which means you can use any programming language supported by Docker.
-
Scaling: AWS Lambda automatically scales the number of function instances based on the incoming request volume, allowing you to handle large loads without manual intervention. OpenFaaS also supports scaling, but it requires manual configuration and setup. You need to specify the desired number of replicas to handle the load.
-
Vendor Lock-in: AWS Lambda is a proprietary service offered by Amazon, which means it ties you to the AWS ecosystem. If you develop functions using Lambda, it may be challenging to migrate them to other cloud providers or hosting platforms. OpenFaaS, being open-source, provides more flexibility in terms of vendor lock-in, as you can deploy functions on different cloud providers or your own infrastructure.
-
Community and Ecosystem: AWS Lambda has a large and well-established community, along with a comprehensive ecosystem of services and tools provided by AWS. OpenFaaS also has a growing community and ecosystem, but it may not be as extensive as AWS Lambda. Depending on your requirements and preferences, the size and maturity of the community and ecosystem can be an important factor to consider.
-
Pricing Model: The pricing model for AWS Lambda is based on the number of requests and the compute time consumed by the functions. You only pay for the actual usage of the functions. OpenFaaS, being a self-hosted solution, allows you to choose your infrastructure and hosting providers, which may have different pricing models. It provides more flexibility in terms of cost optimization.
In summary, the key differences between AWS Lambda and OpenFaaS include deployment and hosting, programming languages and runtimes, scaling, vendor lock-in, community and ecosystem, and pricing model.
